Patented Jan. 16, 1934 v CAP Anthony Zay, Cleveland, Ohio Application February 10, 1932. Serial No. 591,977

3 Claims. (01. 220-) 5 My present invention pertains to a cap that aliords a closure for various types oireceptacles, or the like, or for the covering of an opening to which easy access is desired, as, for instance, the cap for a radiator of an automobile, for the filler spout of an automobile gas tank, for the hub of an automobile, for a jar, or for any other container of fluids, greases or other. materials on which a cap is employed for closing or sealing thesame, and the preliminary object is the provision of a cap for this-purpose which may be readily applied and efiectively looked upon the receptacle, or opening, to obviate the liability of displacement of the cap, regardless of the vibration to which the same may be subjected, and to likewise afiord a sealed joint between the cap and the receptacle.

The invention will be fully and comprehensively understood from consideration of the following detailed description, when read in connection with the accompanying drawing, which form part of the application, with the under standing, however, that the improvement is capable of extended application, and is not confined to the exact showing of the drawing, nor to the precise construction described, and, therefore, such changes and modifications may be made therefrom as do not effect the spirit of the invention, nor the exact scope thereof, as expressed in the appended claims.

In the drawing:

Figure 1 is a bottom view of the cap arranged upon the neck or spout of a receptacle.

Figure 2 is a sectional view of Figure 1.

Figure 3 is a bottom view of the cap locked on a receptacle.

Figure 4 is a sectional view through the improvement of Figure 3.

While my improvement is admirably adapted for use in connection with the radiators, gasoline supply tanks and hub caps for automobiles, and is primarily designed for employment in such'connections, the improvement is not to be restricted in its useful capacityas a closing ele ment for any particular type of receptacle, or for covering any opening where easy access to any mechanism or parts is desired. It will be noted as the description progresses that when in applied position the cap not only eliectively seals the receptacle, or closes the opening, but cannot be displaced therefrom, regardless of any vibra tion to which the same is subjected.

Referring now to the drawing in detail, the numeral 5 designates the neck, or inlet spout. for a substance-containing receptacle.

The neck at its outer end is formed with two inwardly ex-, tending projections 13, subtending two arcs .of equal degree in this particular drawing. There are two projections 12 beyond projections13, with a downward lip, the projections being, lo.- cated diametrically opposite one another.

The cap 13 may and preferably is. of the type to include a round top provided with a depending flange, into which disc 101s inserted and fastened to the cap, as shown in sketch. .The. disc 10 has two rectangular holes, diametrically opposite one another. The header 8 has two projections 9, which are inserted intherecs tangular openings indisc 10 and fastened there;- to. On opposite end of header is a disc that has two equal eccentric curves, with ends of curves diametrically opposite being of equal distance from the center of header 8, as shown at 16. Following along the path of the eccentric curve, the distance from center of header 8 is gradually increased until points 1'? are reached, which are also equal distance from center of header. The spring 7 is designed with a hole in the center to allow header 8 to pass through, resting upon body 6. The arms of the spring rest also on some point of the eccentric curves, depending upon the location, which in Figure 2 is at th minimum distance from the center.

Drawing 4 shows the position of the arms of the spring in a locked position when the maximum distance from the center on a point of the eccentric curve is reached. In the body 6 there is a compressible washer 11, which is in the nature of a disc or ring, and which is in direct contact with projection 13 when the cap is applied.

It will be noted according to the drawing that the spring 7 is under constant tension, whether the cap is in the open position or locked on the neck. This principle causes the body 6 to rest firmly against disc 10. By revolving the cap the fingers of the spring come in contact with projection 12, and by further turning in the same direction the header 8 continues to revolve, causing the arms to go in an outward and upward direction, and when the maximum travel is reached-namely, at points l'I-the cap is securely locked on the neck. In order to release the cap it is revolved by hand force in the opposite direction, when the arms come in contact with the downward projections 12, and continuing the motion of the cap, which further revolves the header, until points 16 are reached, when the cap may be removed from the neck,

[NITED STATES PATENT orFicE the arms having been disposed below the inward projection.

The header 8 is formed from a single plate, with projections 9 parallel with the axis. It will be noted by following the path of travel of the arms, as the header is rotated from an open position that an outward and upward angle occurs. These projections on assembling the cap are inserted through the rectangular holes of the disc 10 and forced over.

Having described the invention, I claim:

1. A cap for a container, the latter having a neck with an inwardly extending lip and from said lip two downward extending projections, diametrically opposite, comprising a rotating head, lock spring resting thereon to normally assume downward angles, a hub formed with said rotating head and passing centrally through lock spring and body and fastened to a disc, to which the cap is fastened so that by rotating said cap will cause the lock spring to contact downward extending projections and continuing rotation will impart an. outward and upward movement of the lock spring for forcing said lock spring in gripping engagement with the extending lip and a washer in the cap and engageable with the lip to provide leak proof connections between the cap and lip.

2. A cap for a container, the latter having a neck with an inwardly extending lip, and from said lip, two downward extending projections diametrically opposite, comprising a rotating head with a flange having two equal eccentric curves diametrically opposite on which rests a lock spring held in position by a hub formed on said rotating head passing centrally through lock spring and body and fastened to a disc to which is fastened a cap, so that by rotating said cap will cause the lock spring to contact downward extending projections and continuing rotation the lock spring riding the said eccentric curves will impart an outward and upward movement for forcing the said lock spring in gripping engagement with the extending lip and a washer in the cap and engageable with the lip to provide leak proof connections between the cap and the lip.

3. A cap for a container, the latter having a neck with an inwardly extending lip, from said lip two downward extending projections diametrically opposite, comprising a rotating head having a flange with two eccentric curves diametrically opposite, lock spring resting thereon to normally assume downward angles, said rotating head having a hub passing centrally through the lock spring and a body and fastened to a disc, and a cap fastened to said disc, the lock spring being under tension said body contacts the disc, so that by rotating said cap will cause the lockspring to contact downward extending projections and continuing rotations will impart an outward and upward movement of the lock spring for forcing said lock spring in gripping engagement with the extending lip, and a washer in the cap and engageable with the lip, to provide leak proof connections between the cap and the lip.
